TECHNICAL FIELD

The present invention relates to a shoe having an active ventilation mechanism, and more particularly, to a shoe having an active ventilation mechanism in which a point on the inside of the sole, where the arch of the foot of the wearer is positioned, is equipped with a pumping member for resiliently supporting and pressing on the arch of the foot and for actively causing inflow of external air and actively ventilating the inside of the shoe by means of pressure, and which is configured such that a comfortable state of foot hygiene can be ensured and that repeated pressure on the arch can correct the shape of the arch and reduce foot fatigue.

BACKGROUND ART

Feet are the most used part of human body and are put on with shoes to be protected from external dirt while walking or running.

The shoe mainly includes natural/artificial leather and covers the external surface of the foot and has a thick insole provided in a lower part of the shoe contacting the ground in consideration of safety and comfort while walking.

The shoe keeps the foot warm from a low temperature environment such as winter, and therefore the inside of the shoes is kept warm and a considerable amount of sweat comes out of the foot.

Particularly, the shoe has a waterproof function to prevent the foot from being dirty or wet by external dirt or rainwater. This function prevents moisture from being absorbed to the inside but also prevents air within the shoe from being discharged to the outside and thus the shoe is less porous.

As a result, the sweat coming out of the foot contaminates the inside of the shoe and causes a bad smell. Also, the inside of the less porous shoe remains wet and the health of the foot is adversely affected by it, causing uncomfortable sense of wear.

A conventional shoe has a particular shape according to size at the time of ex-mill and provides a less comfortable sense of wear. Even though the arch of the foot varies by people, shoes launched in the market have a uniform shape of an arch supporting unit and does not properly meet customers' needs.

BEST MODE

Hereinafter, a shoe having an active ventilation mechanism according to an exemplary embodiment of the present invention will be described in detail with reference to accompanying drawings.

FIG. 1 illustrates an external configuration of a shoe having an active ventilation mechanism according to an exemplary embodiment of the present invention. FIG. 2 is partial cut view of the shoe having an active ventilation mechanism according to the exemplary embodiment of the present invention. FIG. 3 illustrates an entire configuration of a first pumping member of the shoe having an active ventilation mechanism according to the exemplary embodiment of the present invention. FIG. 4 illustrates height adjustment of an expansion and contraction cover of the first pumping member in FIG. 3. FIG. 5 illustrates active ventilation operation of the first pumping member and supporting and pressing state of the arch in the shoe having an active ventilation mechanism according to the exemplary embodiment of the present invention.

A shoe 1 having an active ventilation mechanism according to an exemplary embodiment of the present invention forms an external cover 20 having an entering part 1 provided in an upper part of a bottom plate 10 as shown in FIGS. 1 to 5, and has an accommodation space S formed between an upper part of the bottom plate 10 and the outside. A wearer wears the shoe 1 by entering his/her foot F in the accommodation space S through the entering part 21, wherein a bottom surface B of the foot F is closely adhered to the upper part of the bottom plate 10 and the top of the foot is fixed to an internal wall of the external cover 20.

According to the present exemplary embodiment, a first pumping member 30 is provided in the bottom plate 10 of the shoe 1 to inhale fresh external air and ventilate the accommodation space S with the inhaled external air and to promptly remove sweat and smell from the shoe 1 with the fresh external air introduced by the first pumping member 30.

According to the present exemplary embodiment, the first pumping member 30 is installed in the upper part of the bottom plate 10, and includes a main body 31 which has an upper part open and includes an inhalation pipe 31 b communicating with the outside and a ventilation pipe 31 c communicating with the accommodation space C; and an expansion and contraction cover 32 which closes the upper part of the main body 31 having the open upper part and protrudes upwardly by its own elasticity.

According to the present exemplary embodiment, a circular groove 31 a is formed in an upper circumference of the main body 31 and a circulation projection 32 a formed in a circumference of the expansion and contraction cover 32 is inserted into the circular groove 31 a to fix the expansion and contraction cover 32 to the main body 31 in a sealing state.

A one-way check valve CV is installed in the inhalation pipe 31 b and/or ventilation pipe 31 c to discharge the air inhaled by the inhalation pipe 31 b through the ventilation pipe 31 c.

Referring to the drawings according to the exemplary embodiments, the expansion and contraction cover 32 is formed as small cymbals having a plurality of folding wrinkles 32 b formed in a circumference of the main body 31 and expands and contracts by the folding wrinkles 32 b. An end of the inhalation pipe 31 b as an inhalation path of external air is installed to be higher than a phase of the bottom plate 10 contacting the ground and prevents dirt including external moisture from being introduced to the inside of the first pumping member 31 and the accommodation space S through the ventilation pipe 31 c during the inhalation process of the first pumping member 30 when a wearer walks.

A supporting body 33 is formed in the main body 31 forming the first pumping member 30, and a spring 34 is installed between the supporting body 33 and the expansion and contraction cover 32. The expansion and contraction cover 32 is more expandable and contractable by the elastic force of the spring 34. The reference numeral 36 refers to a washer supporting a lower surface of the expansion and contraction cover 32 and an upper end of the spring 34.

According to the present exemplary embodiment, circulation grooves 11 are formed in an upper part of the bottom plate 10 and the ventilation pipe 31 c of the first pumping member 30 is installed in the circulation grooves 11 to communicate therewith. When the air discharged by the first pumping member 30 moves along the circulation grooves 11, sweat and heat from the foot of a wearer is promptly removed.

The ventilation pipe 31 c having the one-way check valve CV is installed in the circulation grooves 11 to communicate with the outside, and thus air passing through the circulation grooves 11 is discharged to the outside through the ventilation pipe 12.

The one-way check valve CV installed in the inhalation pipe 31 a, the ventilation pipe 12 or the ventilation pipe 31 b guides an air flow only in a forward direction. According to the present exemplary embodiment, the inhalation pipe 31 a and the ventilation pipe 12 or 31 b have a semicircular section, and the one-way check valve CV including a semicircular valve opening or closing the pipe in an air flow direction is installed in the valve body. The semicircular pipe body has a smaller volume than a circular shape and thus does not protrude from the external appearance of the shoes and is accommodated in the shoe stably.

In the shoe 1 according to the present exemplary embodiment, if a wearer wears the shoe 1 and walks after entering the foot F in the accommodation space S through the entering part 21, the expansion and contraction cover 32 of the first pumping member 30 protruding upwardly from the bottom plate 10 is repeatedly pressed by the sole of the wearer, and the first pumping member 30 receives fresh external air through the inhalation pipe 31 b by the repeated pressure of the first pumping member 30 and transmits the outside air to the accommodation space S accommodating the foot F therein through the ventilation pipe 31 c and circulation grooves 11 to promptly remove sweat or smell from the surface of the foot F of the wearer by the transmitted air.

According to the present exemplary embodiment, as shown in FIG. 2, the first pumping member 30 is installed in, and protrudes from, the lower part of the arch A which should be supported or pressed from the foot F of the wearer. Thus, the arch A is stably supported and pressed by the pressure of the first pumping member 30 through the arch A of the foot F, and the foot fatigue is reduced and the shape of the arch is corrected while walking. Fresh external air is introduced to the accommodation space S by the pumping operation of the first pumping member 30 and sweat or smell of the foot F of the wearer is promptly removed.

That is, as shown in FIG. 5, the first pumping member 30 receives external air in the accommodation space S by the repeated pressure of the arch A of the foot F of the wearer. During this process, the arch A is supported and pressed by the repulsive force of the first pumping member 30 and the foot fatigue is reduced and the shape of the arch A is corrected.

According to the present exemplary embodiment, in realizing the shoe 1, the wearer may freely set the projection height of the first pumping member 30 having the supporting and pressing functions for the arch A so that the first pumping member 30 protrudes at the height required for his/her body shape and provides comfortable sense of wear and stable supporting and pressing functions of the arch A.

According to the present exemplary embodiment, the supporting body 33 which supports the lower end of the spring 34 is installed in the bottom surface of the main body and is inserted into the coupling pipe 40 having the coupling groove formed in an internal circumference thereof. A screw thread is formed in an external surface of the supporting body 33 and a screw coupling unit 39 is formed in an internal surface of the coupling groove of the coupling pipe corresponding to the screw thread. Thus, the supporting body 33 moves up and down according to the coupling state of the supporting body 33 and the coupling pipe 40. Accordingly, the strength of the spring 34 is adjusted.

As shown in FIG. 4A, the shoe 1 according to the present exemplary embodiment moves upward when the supporting body 33 fixed to the screw coupling unit 39 of the coupling pipe 40 of the main body 31 by the screw is rotated in a forward direction. Then, the spring 34 and the expansion and contraction cover 32 supported by the spring 34 protrude further. If the supporting body 33 is rotated in a reverse direction as in FIG. 4B, the shoe 1 moves downward and the spring 34 and the expansion and contraction member 32 supported by the spring 34 less protrude.

According to the present exemplary embodiment, a height adjuster 35 is installed in a lifting pipe 33B and passes through the expansion and contraction cover 32 to conveniently provide a rotational force required for lifting the lifting pipe 33B. According to the present exemplary embodiment, the height adjuster 35 is shaped like an angular bolt.

The expansion and contraction cover 32 is separated from the main body 31 and the supporting body 33 is not exposed to the outside. The supporting body 33 is rotated in a forward or reverse direction and moves upward through the rotation of the height adjuster 35 shaped like an angular bolt.

An angular groove 33 a is formed in an internal circumference of the supporting body 33 to improve the degree of assembly. The height adjuster 35 shaped like an angular bolt and passing through the expansion and contraction cover 32 is engaged with the angular groove 33 a to enable a user to rotate the height adjuster 35 in a forward or reverse direction and adjusts the compression degree of the spring 34 elastically supporting the expansion and contraction cover 32 and to adjust the projection height of the expansion and contraction cover 32 and the pressure of the arch A.

Accordingly, the shoe 1 according to the present exemplary embodiment may freely set the projection height of the expansion and contraction cover 32 supporting and pressing the arch A of the sole by adjusting the height of the supporting body 33. Thus, a wearer may adjust the height of the expansion and contraction cover 32 according to his/her body shape and wear the shoe 1 stably.

FIG. 6 is an exploded perspective view of a second pumping member of a shoe having an active ventilation mechanism according to another exemplary embodiment of the present invention.

Referring to the exemplary embodiment in FIG. 6, the pumping member according to the present exemplary embodiment is installed in the arch of the shoe 1 (part corresponding to the internal arch of the foot) and has a worm 38 and a worm wheel 37 corresponding to the worm 38. If the worm 38 is rotated from the outside, the supporting body 33 moves up and down.

That is, the worm wheel 37 is formed in a lower part of the supporting body 33 supporting the spring 34, and the worm 38 is formed to be engaged with the worm wheel 37. A head part of the worm 38 is exposed to the outside to be rotated by the outside of the main body. The worm wheel 37 has an insertion groove formed therein to be inserted with the supporting body 33. A coupling screw 39 is formed in an external surface of the supporting body 33 to be coupled with a screw thread by screw. A screw thread is formed in a vertical direction in an external surface of the worm wheel 37 to be coupled with the worm 38.

With the foregoing configuration, if a user (a shoe wearer) rotates the worm 38 in one direction, the worm wheel 37 is rotated. Accordingly, the supporting body 33 inserted into the internal insertion groove of the worm wheel 37 rotates along the coupling screw 39 and moves up and down.

As shown therein, the height adjuster 35 according to the present exemplary embodiment is shaped like a bolt having a groove 35 a formed in a lower part therein, instead of being shaped like an angular bolt. The height adjuster 35 is fitted to and inserted into the projection 45 b of the coupler 45 in a lower part of the groove 35 a. The spring adjusting bolt 44 inserted into the height adjuster 35 is coupled to an internal screw thread 45 a of the coupler 45 by screw in a lower part thereof. The stopper 46 is coupled to a lower part of the spring adjusting bolt 44 and is held by the lower part of the coupler 45 to prevent the spring adjusting bolt 44 from being separated.

The coupler 45 is inserted into the internal part of the supporting body 33 not to be separated from the supporting body 33. A coupler stopper (not shown) is formed in an upper surface of the supporting body 33 not to separate the coupler 45 from the supporting body 33, and a stopping surface 33 d is formed in an internal surface of the supporting body 33 to stop the coupler 45 to the projection of the coupler 45 during a rotation process.

If the height adjuster 35 rotates in one direction, the coupler 45 having the projection 45 b inserted into the groove 35 a of the height adjuster 35 rotates. Then, the projection 45 b of the coupler 45 pushes the stopping surface 33 d of the supporting body 33 to rotate the supporting body 33. In accordance with the rotation of the supporting body 33, the supporting body 33 moves up and down along the coupling screw 39 within the worm wheel 37.

A projection, stopper or screw stopper is formed in an upper part of the coupling screw 39 of the worm wheel 37 to prevent the supporting body 33 from being separated from the upper part of the worm wheel 37 after reaching a predetermined height by rotation. Then, the supporting body 33 does not move beyond the predetermined height or more. The screw stopper means a stopper which prevents the supporting body 33 from lifting further by a male screw having an upper end cut at a right angle and contacting a female screw having no groove therein.

If the spring adjusting bolt 44 is rotated, the height adjuster 35 remains still and only the spring adjusting bolt 44 is rotated. If the spring adjusting bolt 44 is rotated to the right side, the coupler 45 coupled to the internal screw thread 45 b receives a lifting force. As the coupler 45 is stopped by the supporting body 33 not to be separated from the upper part of the supporting body 33, the spring adjusting bolt 44 moves downward. Then, the spring adjusting bolt 44 presses the expansion and contraction cover 32 and the strength of the spring 34 below the expansion and contraction cover 32 is weaker. If the spring adjusting bolt 44 rotates in a reverse direction, the strength of the spring 34 is weaker by the same reason. Accordingly, the rotation of the spring adjusting bolt 44 may adjust the strength of the spring 34.

The air introduced to the pumping member from the outside of the foot through the inhalation pipe is turned on or off by an inhalation check valve installed in an entrance of the pumping member. That is, the inhalation check valve as a check valve provided in one direction and open or closed according to an air flow direction is installed in an inhalation front end of the pumping member. The ventilation pipe ventilates, circulates (along the circulation groove) and discharges air from the pumping member to the inside of the shoe or the outside of the shoe. A one-way check valve CV which is shaped like a semicircular shape and open and closed along the air flow direction is installed in the part ventilating from the pumping member to the inside of the shoe and the part discharging the air to the outside after circulation.

The ventilation pipe which discharges air to the outside of the shoe communicates with the inhalation pipe and discharges air to the outside of the shoe. The inhalation pipe concurrently inhales and discharges external air. That is, the air is inhaled and discharged by the same inhalation pipe according to the pressure and relaxation of the pumping member.

The inhalation pipe and the ventilation pipe are formed as a steel pipe or PVC pipe having a semicircular pipe body, which has a small volume and easy to be installed. This may also apply to the exemplary embodiment in FIGS. 7 to 10.

FIG. 7 is an exploded perspective view of a third pumping member of a shoe having an active ventilation mechanism according to another exemplary embodiment of the present invention.

Referring to FIG. 7, the third pumping member does not have the worm wheel 37 and the worm 38 unlike the pumping member in FIG. 6. The coupling screw 39 according to the present exemplary embodiment is formed in a bottom surface of the main body.

Like in the exemplary embodiment in FIG. 6, the supporting body 33 rotates and moves up and down by the rotation of the height adjuster 35. The spring is pressed or relaxed by the rotation of the spring adjusting nut 44. The detailed operational principle is the same as that in FIG. 7 and description will be avoided.

A projection, stopper or screw stopper is formed in an external lower part of the supporting body 33 to prevent the coupling screw 39 from being separated after reaching a predetermined height by rotation. The screw stopper means a stopper which prevents the supporting body 33 from lifting further by a male screw having an upper end cut at a right angle and contacting a female screw having no groove therein.

FIG. 8 is an exploded perspective view of a fourth pumping member of a shoe having an active ventilation mechanism according to another exemplary embodiment of the present invention.

Referring to FIG. 8, according to the present exemplary embodiment, the spring is not pressed, and a washer below the expansion and contraction cover 32, a spring below the washer, a supporting body below the spring and a coupler coupled to the height adjuster by screw rotate by the rotation of the height adjuster 35. The height of the supporting body 33 is adjusted by the rotation of the height adjuster 35 along the screw coupler 39 formed in a lower part of the main body.

The washer formed in a lower part of the expansion and contraction cover 32 has a projection groove 36 a formed in an internal central part thereof. The height adjuster 35 is inserted into the projection groove 36 a. The washer rotates by the rotation of the height adjuster 35.

A bending part 34 a whose both ends are bent inwardly is formed in the spring 34. The upper bending part 34 a is coupled and fixed to a lower end of the washer 36, and a lower being part is coupled and fixed to the spring groove 33 e of the supporting body 33. A coupler 35 shaped like a nut is coupled to a lower part of the height adjuster 33. The coupler 35 does not affect the rotation of the supporting body unlike that according to the exemplary embodiment in FIG. 7.

As the height adjuster 35 rotates, the washer 36 rotates. Then, the spring having the upper bending part fixed thereto rotates with respect to the washer. According to the rotation of the spring, the supporting body having the spring groove 33 e coupled and fixed to the lower bending part of the spring rotates.

As above, according to the present exemplary embodiment in FIG. 8, the washer, spring, bolt and supporting body rotate by the rotation of the height adjuster 35 to thereby adjust the height of the supporting body.

A projection, stopper or screw stopper 42 is formed in an upper part of the coupling screw 39 to prevent the supporting body 33 from being separated from the coupling screw 39 after reaching a predetermined height by rotation. The screw stopper means a stopper which prevents the supporting body 33 from lifting further by a male screw having an upper end cut at a right angle and contacting a female screw having no groove therein.

FIG. 9 is an exploded perspective view of a fifth pumping member of a shoe having an active ventilation mechanism according to another exemplary embodiment of the present invention. The fifth pumping member is installed in a heel of the shoe.

In the exemplary embodiment in FIG. 9, the pumping member is installed in a heel of the shoe. A screw thread is formed in an external surface of the supporting body 33 and the screw coupler 39 coupled to the screw thread by a screw is formed in an inside of the main body, i.e. inside of the coupling pipe 40.

The height adjuster 35 has a screw thread formed inside and a stopping surface 35 b formed in an external surface thereof. The height adjuster 35 is inserted into the supporting body and stopped by the stopper 33. That is, the stopping surface 35 b formed in an external surface of the height adjuster 35 is stopped by the stopper 33 d of the supporting body 33. The screw thread formed in the height adjuster 35 is coupled to a coupler 45 shaped like a bolt. The coupler 45 is inserted into the supporting body 33 and coupled thereto not to be separated therefrom. A coupler stopper (not shown) is formed in an upper surface of the supporting body 33 to prevent the coupler 45 from being separated from the supporting body 33.

If the height adjuster 35 is rotated by a tool such as a driver, the stopping surface 35 b of the height adjuster 35 is stopped by the stopper 33 d of the supporting body 33. The supporting body 33 rotates and is adjusted in height by the screw coupler 39.

A stopper or projection is formed in an upper part of the coupling screw 39 of the coupling pipe 40 to prevent the supporting body 33 from being separated after reaching a predetermined height by rotation. Thus, the supporting body 33 does not move beyond the predetermined height.

FIG. 10 is an exploded perspective view of two pumping members installed in an arch and heel of a shoe having an active ventilation mechanism according to another exemplary embodiment of the present invention.

Referring to FIG. 10, the pumping member which corresponds to the arch of the shoe employs the pumping member according to the exemplary embodiment in FIG. 6, and the pumping member corresponding to the heel of the shoe employs the pumping member according to the exemplary embodiment in FIG. 9. However, the pumping members are not limited to those above, and the pumping member according to other exemplary embodiments or those not shown herein may be used.

An expansion and contraction cover 32 of the pumping member according to the present invention may have various shapes including a circular or semicircular shape, and the shape and form of the expansion and contraction cover 32 may be optional according to the need of the skilled in the art.
